抗盐型堵水剂XD-1的研制与应用

THE RESEARCH AND APPLICATION OF PLUGGING AGENT XD-1 FOR SALT RESISTANCE

摘要: 对淀粉在引发剂作用下与丙烯酰胺的接枝产物进行了研究，通过实验确定了最佳反应条件，并用红外光谱对产物的结构进行了证明，同时在性能上与聚丙烯酰胺进行了比较。该接枝聚合物与交联剂间苯二酚、六次甲基四胺交联成冻胶作为堵水荆，通过岩心流动实验发现该冻胶的渗透率较低，在现场施工堵水效果较好。

Abstract: The graft- copolymer S - AM is composed of acrylamide and water - soluble starch, by a series of experiment we found the optimal reactive condition. The structure of S- AM is verified by Infrared Spectra(IR).And its properties of S- AM is compared with PA
